Bands that are good: Exodus (their best album so far is their first, Bonded By Blood, 1985, and I also heard a lot of positive comments on their new album that's coming out this year), Sodom (everything until their Agent Orange album, 1989, is the best, but some of the stuff that comes after that is also pretty good), Kreator (everything is brilliant, especially their albums from 1985, 86, 87, 89, 90, 2001 and 2005. The other albums contained more experimental stuff, but certainly is good too), Slayer (everything until South Of Heaven, 1989, is what makes thrash metal great, this is just brilliant music).
